Optimal Direct Yaw Moment Control Of A 4wd Electric Vehicle, Winston James Wight

Master's Theses

This thesis is concerned with electronic stability of an all-wheel drive electric vehicle with independent motors mounted in each wheel. The additional controllability and speed permitted using independent motors can be exploited to improve the handling and stability of electric vehicles. In this thesis, these improvements arise from employing a direct yaw moment control (DYC) system that seeks to adapt the understeer gradient of the vehicle and achieve neutral steer by employing a supervisory controller and simultaneously tracking an ideal yaw rate and ideal sideslip angle. DYC enhances vehicle stability by generating a corrective yaw moment realized by a torque …

Cfd Study Of Aerodynamic Drag Reduction Tool Of A Generic Sports Utility Vehicle (Suv), Samira Ishrat Jahan

Masters Theses

The Sports Utility Vehicle (SUV) has been a popular automobile choice in North America for over 50 years due to its seating and hauling versatility and good towing capacity. This widespread popularity has resulted in manufacturers pushing for increased horsepower and cabin size. Unfortunately, the limiting factor has been fuel economy which is governed by the vehicle aerodynamics. A reduction in aerodynamic drag can result in better fuel economy. The goal of this study is to reduce the aerodynamic drag of a generic SUV and the efficient application of drag reduction devices to control flow separation. An initial study has …

Autonomous Cars And Driverless Lethal Autonomy, Nyagudi Musandu Nyagudi

Nyagudi M Nyagudi

“The small picture” - make an advanced autonomous /driverless car. Lots of algorithms, sensors, computers and other gizmos. Now get it to take you to work, park itself and seamlessly run your family errands around the city. Taking grandma to the doctor for the medical check-up, getting the children from school, etc. With Radar, Lidar and other sensors, the car steering with ease through the traffic, no driver to pay, that is another plus, fuel/energy efficiency, yet another plus. It is a bold new world and the sky is the limit. Without the resolution of “small picture” issues there is …

Steam, Electricity & Gas : Historical Perspectives On What We Drive Today And Why, Michael Edward Flinton

Legacy Theses & Dissertations (2009 - 2024)

ABSTRACT

The Safety Risks Of Proposed Fuel Economy Legislation, John D. Graham

RISK: Health, Safety & Environment (1990-2002)

Based on, e.g., a comprehensive assessment of what is known of factors influencing automobile safety, previous industry responses to requirements for fuel economy and prior success of regulators in reducing injuries, Professor Graham concludes that pending fuel economy bills are apt to add 1650 fatalities and 8500 serious accidents to the annual highway toll. He also presents several short-term and long-term strategies for simultaneously saving fuel and lives.
